Abstract

The threat of global climate change mainly in term of heat and combined stress is one of the utmost serious concerns for farmers, and have a negative impact on agriculture production and challenging food security worldwide. A field experiment was conducted during Rabi season at Pulse breeding Block, G.B Pant University of Agriculture and Technology, Pantnagar. The objective of this investigation was to effect of shading to mitigate the heat and combined stress as well as the comparison of heat and combined stress in microsperma and macrosperma genotypes. It was laid out in factorial random block design with three replications. The morpho-physiological and yield attributes of both genotypes under varied growth condition at different time interval were evaluated. The microsperma (PL-8) and macrosperma (PL-11) after shading changed their plant height (6% and 5%), NDVI value (5% and 4%), Membrane stability index (9% and 6%), days to maturity (7% and 6%) and total no of grain (15% and 37%) under heat stress while in combined stress it was changed by 8% and 10% in plant height, 9% and 3% in NDVI value,14% in MSI,7% and 3% in days to maturity and13% and 23% in yield. The above finding proves the effect of shading mitigate the damage extent and also increase production of both lentil genotypes (PL-8) and (PL-11).
